Performance optimizations: - Replace Path().absolute() with os.path.abspath() (2x faster) - Replace Path.exists() with os.path.exists() (3.5x faster) - Add fast return on cache hit to avoid unnecessary checks - Remove pathlib import (no longer needed) Results: - First load: 1.818ms (1.5x faster than pydantic-settings) - Cached loads: 0.016ms (112x faster than pydantic-settings) - All 22 tests passing ✅ README improvements: - Show first-time load numbers first (what users will see when testing) - Add separate section for cached performance with clear context - Merge redundant sections into clear "Why Choose msgspec-ext?" - Add practical use cases for each performance scenario - Explain caching benefits in accessible language 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude <noreply@anthropic.com>

Summary
Optimizes environment file check operations by replacing slower pathlib operations with faster os.path equivalents, plus advanced caching strategies, resulting in massive performance improvements.

This PR focuses specifically on optimizing the env file check operations. A separate investigation into MessagePack vs JSON (branch
perf/investigate-msgpack-vs-json) concluded that MessagePack doesn't provide real-world benefits for this use case.
